Ensure continuity of operation of an electric vehicle under fault condition in converter

摘要: Abstract An electric vehicle is a powered by an motor. In most cases induction motors are applied. But clearly with the increasing complexity of electrical/electronic architectures used in vehicles, it possible to generate fault conditions, such as open circuits which provide graceful degradation system performance because three phase motor can't operate even one less phase. To avoid hard, fail-stop behaviors and ensure continuity operation presence this article proposes introduction multiphase voltage source inverter, motor, double star machine drain train that controlled direct torque control under circuits. fact, using strategy allows elimination ripples service. Experimental results illustrate effectiveness proposed scheme.
